in 2019, 1,052 engineering, consulting, epc and construction projects were implemented in china, and 546 projects achieved mechanical completion. based on the national and company key project construction and technology research projects, we successfully completed engineering design, general contracting, construction, overhaul and revamping of zhongan coal chemical, hainan second aromatics project, zhenhai residue hydrogenation, dongjiakou commercial and storage base, zhongke refining & chemical, dalian hengli, zhejiang petrochemical phase i and other projects, with project safety and quality under control.
continuous improvement of engineering service. we carried out "design optimization" and other special activities in an all-round way, strengthened the consulting service business, increased the integration application of key project codes, increased the input of automatic welding machine, increased the proportion of pipeline prefabrication, and constantly improved the project management level. the construction of intelligent engineering achieved initial results. the digital twin breakthroughs of zhenhai refining and chemical project were made. the construction of digital factories such as zhongke, sstpc and gulei were carried out simultaneously. the detailed rules for the implementation of digital delivery of petrochemical engineering passed the review of the company, so as to improve the digital delivery capacity through the construction of digital engineering. while continuously providing customers with high-quality services in the traditional petrochemical industry, it also provided customers with overall solutions in the fields of new coal chemical industry, lng, bio-energy, soil treatment, etc., and gradually realized transformation from a single engineering contractor to an engineering service provider of integrated solutions.
key technological innovation projects completed. 22 key r&d projects were under control. 4 projects such as se coal water (coke) slurry gasification technology, comprehensive treatment of coal chemical sewage and near-zero discharge technology were completed. 6 projects, including the third generation high-efficiency environmental protection aromatics, completed technology and hydrogen purification and supply technology for fuel cell vehicles, were added to the research. the development and industrial application of the second generation of high-efficiency and environmental friendly aromatics successfully started at one time. the projects of 2000-tonne se coal gasification technology industrial demonstration, high slag and low emission heavy oil catalytic cracking technology, and solid super acid c5 and c6 isomerization technology industrial test were completed on schedule and entered the production preparation stage.
